Dumbwaiters are intended to carry goods and foods rather than people. In a restaurant, dumbwaiters are the means of sending food trays and foods from the kitchen to the service lounges. Unlike the elevators, dumbwaiters will have call & send operational buttons with their entrance doors. Installation of dumbwaiters would be almost with many pre-installed components. Carrying capacities of dumbwaiters are ranging from 50 kg to 300 kg with speeds of 0.25 m/s and 0.4 m/s.
